I built a free custom theming layer for ChatGPT with accent colors, typography, layout controls, and AMOLED mode

Been using ChatGPT for long sessions and the default UI just started annoying me. So I added a full theming layer to my free Chrome extension AI Workspace. You can change accent colors, fonts, chat width, spacing, prompt box size, and switch between Light, Dark, and AMOLED black. There’s also a distraction-free mode that hides stuff like the header, footer, and upgrade chip, plus a floating theme switcher for quick changes. The parts I use most myself are the wider chat layout, a taller prompt box, and AMOLED mode at night.
